project, certified Leuze safety consultants assess the solution dynamically safeguards the area of the transfer
station. The area is monitored by two safety laser
scanners. When the vehicle enters the monitored area,
the monitoring dynamically adapts to the vehicle position
and blanks out the AGV footprint from the monitored
area.
The advantage of this solution is that the presence of
people or their entry is continuously monitored. The
vehicle can move through the monitored area during the
loading cycle while the surroundings of the vehicle are
fully guarded at all times.
This means that it is possible to reliably detect
whether a person is walking next to the vehicle. The
safety solution also allows vehicle loads with different
widths and the transport of parts that protrude at the
front. The system works autonomously and can be easily
integrated into the safety circuit of the system via the 2-
channel safety output.

Multi-track transport systems
Multi-track transport systems often require a safety
concept that ensures smooth processes and complete
safety at the same time. The suitable Leuze safety
solution is shown at the example of a pallet discharge via
gravity conveyors, which is fed by a cross conveyor.
Access guarding takes place via two vertically oriented
safety laser scanners. These monitor the entire transfer
area of the cross conveyor. By switching the protective
fields, the protective function is only released for the
conveyor on which a pallet is discharged. The safety
system receives information about which conveyor is used
from system control.
The advantage of this solution is that the entire access
area is completely monitored at all times. It is also easy
to set up and install, as it takes only two safety laser
scanners to safeguard the entire transfer area. No
additional trigger sensors are required. With conveyors in
close proximity, only this solution enables a conveyor-
specific safety concept.
The safety solutions from Leuze are based on
innovative safety concepts that are individually tailored to
the customer’s system layout as part of the project. They
ensure smooth-running processes with gapless safety
and high system availability.
